What is a PBX

A PBX, otherwise known as Private Branch Exchange, is a telephone system within a company that switches calls between company users on local lines while allowing them to share a certain number of external phone lines. It connects the internal telephones within a business and also connects them to the public switched telephone network (PSTN).

One of the latest tendencies in PBX phone system development is the VoIP-PBX, also known as IP PBX, which uses the Internet Protocol to transmit calls.

Pbx’s include telephone trunk lines that terminate at the PBX, a computer with memory that manages the switching of the calls within the telephone system and in and out of it, the network of lines within the PBX and a console or switchboard for a human operator (optional).

Nowadays, there are four different PBX phone system options:

  • PBX
  • Hosted/Virtual PBX
  • IP PBX
  • Hosted/Virtual IP PBX

IP PBX is a software-based PBX phone system solution which helps accomplish certain tasks and delivers services that can be difficult and costly to implement when using a traditional proprietary PABX.

3CX Phone System for Windows is a good example of an IP PBX phone system.
